imageIf you have Hydralift davits for your fast rescue boat, FRC, you should check them, in particular the hydraulic ram eye at the cylinder end warns Marine Safety Forum. The safety following an incident during a man overboard, MOB, exercise. Fortunately no-one was hurt but the potential is evident.

An offshore installation called for a MOB Exercise. Crew boarded the starboard FRC and the launching operation commenced. Suddenly, for no apparent reason, the davit swung out violently damaging the sponson of the FRC. Hydraulic pipes and the stowing frame were also damaged. The FRC crew managed to disembark safely.

The type of failed davit is “Hydralift”, Model: HL6D-3200-MOB & SWL: 3200 Kg. Vessel was relieved and returned immediately to port for repairs and FRC  replacement.

Lifeboat Hooks “real progress”

Mar 202009
 

Early reports from delegates at the 52nd meeting of the International Maritime Organisation’s Sub-Committee on the design of equipment, DE, indicate that significant progress has been made on lifeboat safety under the Life Saving Appliance Code, LSA.

An industry executive tells MAC that the draft language is ‘satisfactory’, but will still had to be approved by the IMO in plenary session.

The last year’s session was met with severe disappointment by the industry when safety issues fell off the agenda under pressure and was dominated by moves to ensure the existence and profitability of the third-party lifeboat maintenance sector.

Lifeboat accidents have increased dramatically, especially during drills, since the introduction of poorly thought-out on-load release hook regulations. Under the regulations, lifeboat releases were designed to fail into an unsafe condition if something went wrong. Lifeboats are not regarded as ‘people carriers’, like building lifts and equipment used in the offshore industry which must ‘fail to safe’ if something goes wrong.. As a result, failure of the release hooks frequently causes serious injury or death.

Incidents have been blamed on poor training and maintenance by seafarers but poor lifeboat design, unclear signage, badly written manuals, operating procedures, and poorly designed release systems are common.  Counterfeit equipment and ‘copycat’ releases made of under-specification materials are addition factors.

Watch That FRC Winch

From Marine Safety Forum

As part of an abandon ship exercise there was an emergency launch of the FRC. When recovering the FRC the davit winch did not seem to have full power. Just as the FRC was a deck level it started to fall. The davit driver was unable to hold the FRC, and it suddenly fell approximately 3 metres and landed in the water. The FRC crew member injured his leg.

Following x-ray it is confirmed that both bones in leg are broken and will require surgery.

Injured Person likely to be off work for 6/8 weeks.

Immediate Cause

Mechanical failure in the winch motor caused the FRC to fall. In this situation there is no brake that may stop the winch wire from running out.

Mechanical Failure

The motor is being investigated by the supplier to look for causes of failure. The maintenance of the motor was up to date and the maintenance and certification of the FRC/Davit system is up to date.

Conclusion

It was agreed between the investigation parties that his incident occurred due to a technical failure in the winch motor. The winch motor has been removed and sent to the davit supplier for further investigation.

Vessel Actions

The Master has decided that no Crew members will be on board the FRC when conducting emergency launching exercises

Improvement to the davit system is required to avoid misunderstandings during operations

Training in the use of the davit – at present only one Officer is trained for the davit operation – more persons to undergo training.
