STANDARDS & PROJECT CRITERIA
The governing basis comes first.
Use the vessel’s approved trial agenda, building specification, maker data, relevant IMO/ISO/class rules and owner requirements. Resolve conflicts between criteria before trials begin and identify which body has final acceptance authority.

SERVICE FAQ
Questions project teams ask.
Every scope is confirmed against the actual vessel, timing and decision requirement.
01How early should trial planning start?+
Ideally during the design or commissioning phase, and at minimum before the final trial agenda is fixed.
02Can multiple surveys run during one sea trial?+
Often yes, but operating conditions, staffing, sensor setup and interference must be coordinated carefully.
03What if the required operating condition cannot be achieved?+
Record the limitation and agree whether an alternative condition, engineering justification or repeat trial is acceptable to the responsible parties.
04Can you attend on behalf of the owner?+
Independent technical attendance can be scoped, but contractual authority and reporting lines must be defined.
