MASS UK Industry Conduct Principles and Code of Practice 2022 (V6)

8.12.8 Specific techniques ensure that mistakes and errors are avoided across the entire life-cycle. Errors introduced
anywhere from the initial concept, risk analysis, specification, design, installation, maintenance and through to
disposal could undermine even the most reliable protection. IEC 61508 specifies techniques that should be used
for each phase of the life-cycle. The seven parts of the first edition of IEC 61508 were published in 1998 and
2000. The second edition was published in 2010.

8.13 MASS DISPOSAL
9.1 OBJECTIVE
8.13.1 MASS, for the purposes of this Code, will follow the existing legal policies and practices already in place for
manned ships when an owner decides to dispose of its MASS.
The objective of this Chapter is to provide guidance on the lights, shapes and sound signals required
by MASS.
8.13.2 Disposal will take two forms. These are:
n Disposal by sale to new owner;
n Disposal by sale to a ship breaker as a MASS end of life activity, which is known as Recycling..
8.13.3 Disposal by Sale. MASS owners will follow the existing maritime ship sale processes as agreed in maritime law.
This may include the use of a ship broker to facilitate the sale to a third party. The selling process usually involves
three stages. These are:
n Negotiations and Contracts Stage;
n Inspection Stage;
n Completion Stage.
8.13.4 Memorandum of Agreement (MOA) will be drawn up by the shipbroker on behalf of the MASS owner. The MOA
is the formal contract of sale of the MASS. MASS owners will, where possible, take advantage of the existing
standard forms of MOA contract, one example being the Norwegian Sale Form (NSF). For a UK Registered
MASS, the sale must be accompanied by an MCA Bill of Sale document, or similar for overseas nations.
8.13.5 Disposal by Recycling. MASS owners will follow the current recycling process and procedures as laid out in
National, Regional and International law.
9.2 SCOPE
9.2.1 If it can be demonstrated that, for a particular MASS, full compliance with the regulations is impracticable, then
application can be made to the Administration where considered necessary, via the RO, for consideration of
exemptions and equivalent arrangements, taking into account the class and nature of the operation of the MASS
concerned.
9.3 LIGHTS, SIGNALS & SHAPES
9.3.1 A MASS should comply with the requirements of the International Regulations for Preventing Collisions at Sea,
1972, as amended (COLREG). With regard to Part C, a MASS which operates only between sunrise and sunset,
and in favourable weather, is not required to carry navigation lights.
9.3.2 Table 9-1 is a summary table of navigation lights appliances for MASS. This Table is for guidance only and does
not cover all possible operations. Reference should be made to the regulations stated in Paragraph 9.3.1 for all
operations not covered.
8.13.6 MASS ship builders will ensure that each vessel is supplied with an Inventory of Hazardous Materials (IHM).
8.13.7 MASS owners will ensure that the IHM is maintained during the period that they own the MASS platform.
8.13.8 MASS owners when disposing of a MASS platform for recycling will ensure that the IHM is up to date.
8.13.9 There are a number of guides on the recycling of ships that are applicable for application to the recycling of
redundant MASS. The following is one example.
