About Us

Mecal’s 24 Years of continued growth

MECAL was founded in 1993 as “Marine Engineers Certifying Authority Ltd” by the Institute of Marine Engineering, Science & Technology & we still maintain close links with the Small Ships Group of the Institution.

Since then MECAL has grown to become one of the leading Certifying Authorities, directly authorised by the UK Dept for Transport (Maritime & Coastguard Agency) and other Red Ensign Group Flag States, for commercial vessels & workboats up to 24m load line length and for larger vessels under specific delegation.

We are also working with the MCA in the development of the new 500GT Cargo Ship & Workboat Code & in the emerging field of autonomous vessels where we have a particular speciality.

We currently have in excess of 1500 commercial vessels on our register with increasing bias towards the larger complex workboats.

MECAL has an extensive network of surveyors and naval architects in the UK, Europe and Worldwide. Our senior personnel include ex class society & MCA surveyors & naval architects, well versed in applying the high ‘’class’’ standards in this sector. Our professional standards are based on MCA appointment criteria & on Continuing Professional Development (CPD) policy set by the Engineering Council.

MECAL is driven by its Technical & Professional Standards Committees through it’s comprehensive Quality Assurance system. Part of the Technical Committee function is to issue technical guidance to our worldwide network of surveyors, naval architects & specialists to provide support and to facilitate consistency in interpretation of the Codes of Practice.
