Question 1

Which separate MGN specifically addresses the use of overside working systems (e.g. rail and trolley systems) on commercial yachts, small commercial vessels and loadline vessels?

Accepted Answer

MGN 578 (M), which covers track/trolley overside working systems and includes a static load test requirement (commonly 12kN) for installation approval MGN 578 is the dedicated guidance for engineered overside-working track/trolley systems, requiring installation drawings to be submitted for approval and installation testing to be witnessed by the MCA, Class, or an appropriate certifying authority, including static load testing.

Question 2

What is the formal name and statutory instrument number of the regulations underpinning MGN 410 (M+F), the MCA's core work at height guidance?

Accepted Answer

The Merchant Shipping and Fishing Vessels (Health and Safety at Work) (Work at Height) Regulations 2010, SI 2010/332 These are the actual UK statutory instrument ("the WAH Regulations 2010"); MGN 410 is the MCA's guidance on how to comply with them, not the law itself. The regulations came into force on 6 April 2010, implementing EU Directive 2001/45/EC.

Question 3

If there is ever a conflict between the WAH Regulations 2010 (as supported by MGN 410) and the Code of Safe Working Practices for Merchant Seafarers (COSWP), which takes precedence?

Accepted Answer

The WAH Regulations 2010 and MGN 410 take precedence, since COSWP is guidance while the WAH Regulations are statutory law MGN 410 explicitly states this precedence: where the two sources conflict, the legally binding WAH Regulations 2010 (and the MGN supporting them) override COSWP, which remains valuable general guidance but is not itself a statutory instrument.
