INTRODUCTION Introduction Image

Offshore Maritime Ltd was founded in August 2006 by Jim Halligan who operates the company by offering a personal service to his clients in providing either survey or consultancy work or as often found, a combination of both.

Since leaving a seagoing career having over seven years experience in the rank as a Chief Engineer, Jim has spent nearly 20 years as a surveyor and consultant working in both the marine and offshore environments – which has included a leading Classification Society and London based marine and offshore surveyors before establishing Offshore Maritime Ltd as a Director of his own company.

Services have been provided to existing engineering, surveying and consultancy establishments. The experience of working with other companies, has had the benefit of developing affiliations enabling us to respond to enquiries requiring the skills of Naval Architect(s), Mechanical Engineers, Master Mariners, etc.

In providing services as Offshore Maritime, it has been particularly important to ensure that clients are satisfied with the end product for each and every project worked on and while not soliciting responses for the services provided, it has been rewarding to often receive written recognition for the services provided as follows:

Thruster Installation Manager role :
“Thanks for your help and effort with all of this. An excellent job well done despite all of the issues the team had to face...”
