Fatality after capsize of workboat with eight persons onboard
A workboat capsized during a night-time personnel transfer to a cargo barge, leaving seven people in the sea and one dead. The flash examines an unremoved self-righting safety pin, maintenance shortcomings and inadequate remote man-overboard arrangements, and suggests changes to transfer procedures, rescue exercises and equipment checks.

Tug capsized during operations
A stern tug girted and capsized while assisting a heavily laden barge entering port; its crew escaped uninjured. The flash discusses unstable stern towing, excessive speed, absent gob wire, emergency-release unfamiliarity and inadequate coordination. Lessons address towing arrangements, competence, risk assessment, toolbox talks and working-time compliance.

Parting of trawl wire on converted scallop dredger Olivia Jean with 1 person injured
MAIB investigates a fisherman’s injury aboard Olivia Jean off Beachy Head when a trawl wire parted during gear recovery and bridle chains fell onto him. The failure mechanism remained uncertain because wire ends were discarded. The report examines equipment maintenance, vessel modifications and stability, crew rest, medical assistance and regulatory oversight.

MAIB Safety Digest 2010 — Fishing edition
This fishing safety digest examines separate casualties involving grounding, flooding, fire, capsize and crew overboard, alongside fatigue and gear-handling injuries. Lessons address navigation, watertight integrity, emergency drills, lifejacket servicing and safe winch arrangements. Cases distinguish uncertain flooding origins and alternative fire causes from established equipment deficiencies.

Girting and capsize of tug Ijsselstroom
Investigation of Ijsselstroom’s girting, capsize and sinking at Peterhead during stern towing while moving astern. It examines hydrodynamic and static stability, absent bridle protection, towing-winch release arrangements and wheelhouse ergonomics. Findings and recommendations address skipper training, operational briefings, risk assessment and port oversight; fatigue was not considered contributory.

Girting and capsize of tug Flying Phantom while towing bulk carrier Red Jasmine with 1 person injured and loss of 3 lives
Investigation of Flying Phantom’s fatal girting and capsize while assisting Red Jasmine on the River Clyde in thick fog. It examines delayed towing-winch emergency release, reduced stability with an open watertight door, blind-pilotage arrangements and deficient port risk management. Recommendations address restricted-visibility towage limits, training and independent safety-management assurance.

Jack-up (self-elevating) installations: floating damage stability survivability
This information sheet addresses research indicating that existing jack-up damage-stability survivability criteria may be inadequate in certain environmental conditions. It advises reassessment of installation capability and caution during wet towing, with reviews of contingency arrangements, crew instructions and training to support rapid evacuation, escape and rescue following significant flooding.

Engine room flooding
A ship flooded during preparations to clean a seawater inlet filter, causing a significant port list and extensive equipment damage. Although valves tested correctly, insufficient closure was suspected. Lessons address valve isolation, securing remote operation, filter-cover cleat sequencing and continuity of responsibility during cleaning.
