All GSS Workboats comply with the Maritime and Coastguard Agency Code of Practice.


GSS is a member of the National Workboat Association (NWA).


The NWA was formed in 1994 to assist in the formulation of the Maritime and Coastguard Agency Workboat Code of Practice. The practical guidance and liaison between the parties proved mutually beneficial, each group gaining an understanding of the other’s viewpoint. The cooperation continued as the Workboat Code of Practice developed and became law. Work continues to resolve anomalies and misinterpretations to produce a harmonised, workable Code of Practice.


GSS Marine Services is now accredited to CHAS – the Contractors Health & Safety Assessment Scheme – a major accreditation website used by local authorities, government departments and large private companies as a means of pre-qualification when applying for contracts. CHAS gives potential clients assurance that the contractor meets clients’ health and safety standards.
