Foreword The MCA are mindful of the part we have to play in the hydrographic sector, and the responsibility we carry for facilitating relationships between those who gather the data, and those who want to use it. Over the past decade or so, despite reductions in public spending, effective, genuine collaborations and partnerships have been established between data gathering programmes, and public-sector organisations, govt. departments, and with research and industry partners. As a result, hydrographic data and marine geospatial products are increasingly considered valuable, especially when married with modern survey standards and emerging acquisition technologies.
The usefulness of hydrographic data for wider, non-safety related uses particularly across Government has contributed towards development of improved products, collaboration and inter-operability capabilities and provided better value for all. The MCA liaises closely with industry, research institutions and business stakeholders to assess and review marine innovation and emerging hydrographic technologies, and advances in data processing and visualization. The MCA are well positioned to take advantage of these developments and envisage being able to leverage potential efficiencies in the future to provide high quality data and improve maritime safety and the marine environment.

Introduction As an Executive Agency of the Department for Transport (DfT), the Maritime & Coastguard Agency (MCA) plays a unique role within Government in discharging statutory hydrographic obligations under the United Nations’ Safety of Life at Sea (SOLAS) Convention. Working in association with the UK Hydrographic Office (UKHO), the MCA funds and delivers the UK Civil Hydrography Programme (CHP), which delivers these SOLAS obligations to reduce the number of maritime incidents, the associated potential for loss of life, vessels, equipment and damage to the marine environment caused from polluting incidents at sea.
The CHP prioritises areas of highest
navigational safety risk and surveys and maps
UK home waters - defined by the boundaries of
the UK’s Exclusive Economic Zone, an area in
excess of 720,000km2 - in order to keep our
nation’s nautical charts and publications
current, safe and fit for purpose.
The CHP makes extensive use of geographic
information systems (GIS) to prioritise survey
areas using a contemporary risk analysis
methodology capable of reflecting the changing
pressures of the maritime sector.
The hydrographic survey work commissioned
for the CHP is undertaken by contractors, who
gather and report seabed data using their own
personnel, equipment and vessels. The core
CHP work scope has been divided into the
following streams:
• Routine resurvey - navigationally critical
shallow water areas with mobile seabed;
• Shallow water - predominantly 0 to 40m
water depth; and
• Shallow to medium water - 0 to 200m
water depth.
To support the requirements of the CHP, the
MCA specifies state-of-the-art survey
technologies including high resolution
multibeam echosounders (MBES) and Real-
Time Kinematic (RTK) Global Positioning
Systems (GPS) to ensure accurate high quality
hydrographic information is gathered.
Additionally, more focused work includes high-
resolution wreck investigations, water column
data collection and seabed grab sampling.
Prior to final data being accepted from
contractors, it passes through a rigorous quality
assurance process at the UKHO’s Bathymetry
Scientific Analysis Group, where checks are
made against items such as data density,
interline consistency, geodetic parameters and
tidal observations. Once data has passed
validation, it is archived to the UKHO’s
bathymetric database ready for inclusion in
their nautical charting products.
The UKHO hosts the Marine Environment Data and Information Network (MEDIN) Data Archive Centre (DAC) for bathymetry data. Bathymetry data collected through the CHP are made freely available to visualise and download from https://www.gov.uk/guidance/inspire-portal-and-medin-bathymetry-data-archive-centre The British Geological Survey hosts the MEDIN DAC for geology, geophysics and backscatter data. Backscatter data collected through the CHP are made freely available to visualise and download from http://www.bgs.ac.uk/GeoIndex/offshore.htm
The MCA regularly collaborate with other
public-sector organisations in order to increase
efficiencies under the ‘gather once, use many
times’ philosophy. The MCA have made the
CHP more accessible by:
• Sharing UK CHP Hydrographic Survey
Specification
• Making CHP data accessible via the
MEDIN bathymetry DAC and
backscatter DAC
• Providing British Geological Survey
CHP seabed samples for further
analysis

News from the CHP Hydrography and Meteorology
Team
The MCA Hydrography and Meteorology
(HydroMet) team comprises:
Hydrography and Meteorology Manager –
Andrew Colenutt
Hydrography and Meteorology Technical
Lead – Robert Kinnear
Hydrography and Meteorology Programmes
Lead – Paula English
Hydrography and Meteorology Programmes
Coordinator - Rebecca De Bono
The Navigation Safety Branch, led by Assistant
Director, André Cocuccio, comprises the
HydroMet team, Maritime Surveillance team,
Navigation Safety Policy team, and the Radio
Spectrum and Technical Standards team.
CHP Survey Contracts
Commencing in 2013, initially for a 3-year
period, commercial survey contracts were
awarded to deliver the CHP’s requirements in
order to improve maritime safety around the
British Isles by surveying UK waters for the
update of nautical charts and publications.
These contracts were extended for a further 2
years, and will be ending March 2018.
The current CHP work scopes have been
awarded to the following marine survey
contractors following a rigorous competitive
tendering exercise:
• Routine Resurvey: EGS International Ltd
• Shallow Water: Gardline Ltd
• Shallow to Medium Water: MMT (UK) Ltd
The MCA HydroMet team have prepared the
tender documents for the new round of CHP
contracts, which are due to commence in April
2018. As part of this process, elements of the
work scope relating to survey prioritization,
analysis and reporting have been revised to
maximize efficiencies and deliverables, and
provide best value for money. Working closely
with colleagues at the UKHO, the team have
also reviewed and updated the UK CHP Survey
Specification.
CHP 2017/18 surveys
In addition to delivering the full proposed
programme of high priority areas, the MCA
HydroMet team secured further funding for an
additional 2 high priority areas. In total, 13 CHP
surveys have been conducted during 2017/18,
covering approximately 5,400km2 of seabed:
HI 1334 North Coasts of Yell and Unst
HI 1498 Eastern Approach to Solent
HI 1501 Porthcawl to Barry
HI 1502 Gower Peninsular to Scarweather
Sands
HI 1504 South Scillies TSS
HI 1505 West Scillies TSS
HI 1512 Yell to Lerwick
HI 1515 Haisborough Sands to Outer Dowsing
Channel
HI 1519 Goodwin Sands to North Foreland
HI 1545 East Anglia RRS
HI 1546 Thames Estuary RRS
HI 1547 Dover Strait RRS
HI 1576 Swansea Bay (funded by Vale of
Glamorgan Council on behalf of the Swansea
and Carmarthen Bay Coastal Engineering
Group)
The following surveys were also considered
under the auspices of the CHP:
HI 1542 Isle of Grain to Leysdown
(commissioned and funded by the Southeast
Regional Coastal Monitoring Programme)
HI 1543 Sunderland to Redcar (commissioned
and funded by the Northeast Regional Coastal
Monitoring Programme)

Civil Hydrography Annual Seminar 2018 The MCA annually convene the Civil
Hydrography Annual Seminar (CHAS). This
year’s event was hosted by the International
Maritime Organization, in London on 7th March.
CHAS is the only Government-led marine event
of its kind that opens its doors to the UK
hydrographic survey and seabed mapping
community.
The aims of CHAS are three-fold:
• To provide an open forum for public
sector organisations to come together
to share data gathering programmes for
the forthcoming years
• To encourage co-operative working and
survey planning integration
• To realise the financial benefits of co-
funding such work.
With over 85 attendees representing nearly 40
organisations, the event has proved as popular
and relevant as ever.
The MCA advocate a coordinated and
integrated approach to the longer-term survey
planning, which hopefully will enable the
hydrographic sector to manage funding
streams more effectively, develop new
partnerships and strengthen existing
collaborations between stakeholders.
Other key factors instrumental in advancing the
hydrographic sector and establishing efficient
ways of working include making high resolution
bathymetric data freely available under the
Open Government Licence and the stronger
adoption of the UK CHP Survey Specification.
In addition, there is a positive approach within
the sector for exchanging ideas and problem
solving in relation to data acquisition,
processing and interpretation.

Collaboration & Partnerships
Within the hydrographic community, effective, genuine collaborations have been established between public sector organisations, government departments and with research and industry partners. Sharing medium-term survey programmes and working together through partnerships and MOUs has enabled survey capability to be taken forward within and between organisations whilst maximising the leverage of public-funded survey assets and resources. A number of successful partnerships with the
MCA have arisen out of CHAS - most notably,
the EU-funded ‘INIS Hydro’ seabed mapping
project and with the National Network of
Regional Coastal Monitoring Programmes
(RCMPs) through close collaboration with the
Channel Coastal Observatory (CCO).
Regional Coastal Monitoring
Programmes
The Memorandum of Agreement to carry out
nearshore bathymetric surveys of the English
Coastline now has signatories from the
following Lead Authorities of the National
Network of Regional Coastal Monitoring
Programmes (RCMPs): New Forest District
Council (Southeast RCMP); Teignbridge
District Council (Southwest RCMP);
Metropolitan Borough of Sefton (Northwest
RCMP); and Scarborough Borough Council
(Northeast RCMP).
Under this MOA, all data gathered under these
RCMPs are made freely available under the
Open Government Licence; are collected
using the UK CHP Survey Specification; and
submitted under the UK Civil Hydrography
Programme to additionally support the update
of nautical charts and products by the UK
Hydrographic Office.
In 2017/18 the Southeast and Northeast
RCMPs commissioned and funded inshore
surveys extending inshore to a defined Mean
Low Water contour of the Isle of Grain to
Leysdown (north Kent) and Sunderland to
Redcar CHP survey area, respectively.
An agreement with the Vale of Glamorgan
Council (on behalf of the Swansea and
Carmarthen Bay Coastal Engineering Group)
is also being developed, which may be
expanded further to enable future
collaboration with the Welsh Coastal
Monitoring Programme.
MPA Evidence Gathering
Programme
Since 2013, CEFAS (Centre for Environment,
Fisheries and Aquaculture Science) under the
auspices of DEFRA (the Department for
Environment, Food and Rural Affairs) has
collected seabed mapping data to underpin
evidence gathering for marine protected area
designation.
The development of a joint MOA and adoption
of the UK CHP Survey Specification will
enable data gathered for environmental policy
making to also be suitable for the operational
update of nautical charts. This approach
ensures the potential for maximum data re-use
and in turn, reduced cost-burden to HM
Government.
Working in close partnership with the CCO,
RCMPs Lead Authorities, CEFAS and others,
realises cost savings and efficiencies by
combining resources, expertise and technical
advice to achieve surveys to IHO Order 1A in
areas of mutual interest. Further collaborative
surveys are scheduled in the forthcoming
years.

How the MCA gathers hydrographic data
Hydrographic survey is the process of gathering a wide variety of data for the purpose of describing
the seafloor. To ensure that data is collected to the highest possible quality for navigational charting,
the MCA specify the following requirements.
Standards Quality Assurance
All surveys are conducted to the IHO Order 1a
survey standard, as defined by the
International Hydrographic Organisation (IHO)
publication ‘Standards for Hydrographic
Surveys, Special Publication S44, Edition 5’,
with the exception of single-beam
echosounder (SBES) check lines under the
Routine Resurvey Programme.
Technical Requirements
Multibeam Echsounder (MBES)
• Multibeam bathymetry is collected during
all CHP surveys.
• The MCA usually require 100%
bathymetric coverage in all areas they
survey.
• System detection capability is defined by
IHO requirements. Contractors are
required to detect objects whose size is
greater than a cube measuring 2m3, in
water depths of up to 40m, and a cube with
sides equal to 10% of depth in deeper
waters.
• A minimum of 9 soundings per minimum
detectable object are required.
• Sound velocity measurements are
routinely taken throughout the survey in
order to position the soundings correctly.
• Contractors are often required to conduct
tidal-stream observations at particular
locations.
Data Quality Control
• In addition to QC procedures employed by
CHP survey contractors, technical
personnel from both the MCA and UKHO
routinely visit contractors’ vessels
throughout survey operations to verify data
quality.
• Prior to final survey data being accepted
from contractors, it passes through a
rigorous quality assurance process at the
UKHO, where checks are made for items
such as data density, inter-line
consistency, geodetic parameters, tidal
observations etc.
• Contractors are asked to provide error
budgets prior to and after every survey so
that the contribution of individual error
sources are tightly defined. This ensures
rigorous quality control of the final survey
dataset.
Additional Measurements
• Rigorous tidal reduction is required on all
CHP surveys.
• Depths are reduced to Chart Datum (CD).
• Seabed grab samples are typically taken
at 5km intervals to ground-truth multibeam
backscatter observations.
• MBES water column data is collected over
all found wrecks to support an assessment
of their condition and ensure shoalest
depth is found.

Propose a Survey Should you know or be aware of any areas of UK seabed that require update to the nautical charts
and publications that cover them, please let us know. The MCA assess CHP survey areas using a
contemporary risk-based methodology, but we are keen to receive any information that can aid us
in our responsibilities to the mariner and the safety of life at sea. E-mail your suggestions for
hydrographic survey to: [email protected]
Typical indications of an area requiring re-survey are:
• Old underlying survey data (check using the "Source Data Diagram" on the latest chart);
• A change in traffic patterns (e.g. increases in cruise ship visits);
• An accident occurring due to inaccurate or incomplete survey data; or
• Changes to the seabed due to sandwave movement / channel migration.

Survey SafetyMuch of the hydrographic work completed by the CHP is undertaken by contractors who are required
to gather seabed data using their own personnel, and vessels owned or chartered by themselves.
Acquired data is then submitted to both the MCA and UKHO.
I. Any vessel undertaking work on behalf of
the CHP must adhere to MCA safety and
regulatory guidelines. MCA safety
requirements include:
II. Contractors are required to supply and
adhere to a Safety Management Plan at all
times.
III. All offshore personnel are required to have
a valid medical certificate to at least the
ENG1 standard.
IV. All offshore personnel are required to have
appropriate and valid safety training
certification.
V. Every vessel that participates in CHP
survey operations is subject to approval by
the MCA (via MCA marine office
inspection) prior to work starting. Repeat
inspections are undertaken annually for the
duration of MCA contracts.
VI. Paris MoU. Should a vessel employed on
the CHP develop a high ship risk profile
(HRS), then the MCA reserves the right to
remove said vessel from the contract until
she meets ‘standard’ (SRS) or ‘low’ (LRS)
risk criteria.
VII. All vessels participating in CHP surveys
are visited by an MCA or a UKHO contract
overseer at least once every 2 months. A
report covering each visit is kept on file by
the MCA HydroMet team. Visits are
primarily intended to focus on the quality of
survey procedures and deliverables, but
also include an informal safety
assessment. If significant safety concerns
are raised, then the contract overseer is
required to notify the local MCA marine
office.
Hydrographic Notes
Reports of any newly discovered dangers to surface or sub-surface navigation are passed
immediately by the CHP contractors to the MCA and UKHO using the H102 Hydrographic Note form.
The nature of the CHP means that H-Notes are regularly sent in. This information is then immediately passed on to the mariner. During survey operations in 2017/18, over 130 H Notes were submitted.
Wreck Investigations All wrecks found in a CHP survey are investigated with additional lines and detailed bathymetry and water column data. Sitting proud of the seabed, wrecks and other man-made obstructions often form the critical depth in a given area of seabed. It is therefore crucial we have confidence that the shoalest point on these obstructions are found so the mariner can navigate safely.
Civil Hydrography Annual Seminar 2018

Sharing Data with the MCA If you are considering performing a hydrographic survey and are willing to share your data with us,
we can pass it on to the UK Hydrographic Office to help them compile new or updated nautical charts
and so help improve safety for mariners.
Your survey does not need to be carried out to full charting standards to be of use. Even without a
full search for dangers, a modern survey can improve on our knowledge of the seabed. There will
be no legal liability on you for the way that we use your data.
The MCA are always happy to give help and advice on hydrographic data gathering requirements in
order to increase the usefulness of hydrographic survey data. Ideally bathymetry data would be
rendered and delivered in digital form, with:
• Data in one of the following: CARIS HDCS
directory (i.e. “HIPS”), Generic Sensor
Format, Fledermaus PFM or ASCII xyz
• Spurious data cleaned from the final,
delivered, dataset with rejected
soundings included, but flagged as
deleted
• Details of the method used for data-
cleaning
• Digital data as full density (i.e. prior to
any gridding or binning being applied),
though if gridded datasets have been
created then please include these too
• The soundings reduced using observed
tides (not predicted tides from Tide
Tables)
• Depths referenced to Chart Datum for the
area.
A report of the survey that describes how the
data was gathered and processed would be of
use, especially if it includes:
• A list of the equipment and software
used;
• How positioning equipment was set up,
calibrated and used;
• How the echo-sounder transducer was
set up and levelled, together with all
sensor offsets;
• Details of the horizontal datum to which
the positions are referred (or the grid, if
appropriate);
• How tides were measured, how the tide
pole or tide gauge was levelled and how
depths were reduced to chart datum.
Data which fully complies with all aspects of
IHO Order 1a would be ideal.

Guidelines for Offshore Developers
The MCA have issued guidelines which are
intended to aid developers when submitting
consent applications which impact upon
hydrography. These guidelines should be read
in conjunction with Marine Guidance Note
(MGN) 543 which replaces MGN 371. They are
available on the MCA pages on gov.uk.
The MGN 543 guidance note highlights issues
that need to be taken into consideration when
assessing the impact on navigational safety
and emergency response (search and rescue,
salvage and towing, and counter pollution)
caused by offshore renewable energy
installation developments. It applies to
proposals in United Kingdom internal waters,
Territorial Sea and Exclusive Economic Zone.
Survey Requirements
All hydrographic surveys should provide full
seafloor coverage that meets the requirements
of the IHO Order 1a survey standard. Particular
attention should be given to horizontal and
vertical sounding accuracy, together with target
detection requirements and, we would request
that all data and reports are passed on to the
UKHO for the update of the UK’s nautical charts
and publications.
MGN 543: Hydrography
In order to establish a baseline, confirm the safe
navigable depth, monitor seabed mobility and
to identify underwater hazards, detailed and
accurate hydrographic surveys are required of
the development at the following stages:
Pre-consent: The site and its immediate
environs extending to 500m outside of the
development area shall be undertaken as part
of the licence and/or consent application. The
survey shall include all proposed cable route(s).
Post-construction: Cable route(s).
Post-decommissioning of all or part of the
development: Cable route(s) and the area
extending to 500m from the installed generating
assets area.
Any additional hydrographic survey undertaken
for any other purposes should be carried out to
the standard described in section 6.c.
The development may result in an alteration to
maritime traffic patterns as vessels seek
alternative passage around the installed
generating assets area. Where this is the case,
it may be considered necessary that a
hydrographic survey of these alternate
passages and their immediate environs
extending to 500m be undertaken. MCA can
provide guidance here if required.
All hydrographic surveys listed above should
fulfil the requirements of the MCA’s
‘Hydrography Guidelines for Offshore
Developers’ and ‘Post-Construction
Hydrographic Guidelines for Offshore
Developers’, which are both available on the
MCA website.
Where to Deliver
On completion of each survey, the bathymetric
data and associated report of survey should be
delivered to the MCA. The MCA is responsible
for collecting and supplying data to the UKHO
to update nautical charts and publications for
the purposes of navigation safety. The
commercial sensitivity of your data will be
respected at all times.
