Dacon Rescue Scoop Design Guidelines

Brief Introduction Dacon Rescue Scoop satisfies the requirement of power assisted means of recovery of both able and

disabled/unconscious persons directly from the water onto the Standby/Rescue Vessel. This guide

provides some advice for designers, yards and owners on what to consider in order to ensure a

successful installation.

The Dacon Rescue Scoop is attached to the vessel in the inner end and operated with the crane in the

outer end. The vessel is maneuvered up to the person in distress. Then maneuvers at dead slow to

catch the person in the net and gently roll him up to the railing where he is received and taken to

safety. More information on the product can be found in our brochure or on our web site.

Rescue Zone The area where the Dacon Rescue Scoop is fitted should be arranged with one or more large

openings above railing height. The openings should cover most of the Dacon Scoop length in order to

get easy access to the person being rescued. Two doors as a substitute is not a good solution for

rescue since the person in the Rescue Scoop may well be unconscious and end up between the two

doors making it very difficult to retrieve him from the net.

Stowage / Location

The Dacon Rescue Scoop needs to be stored in or above the rescue zone in order to be ready for

quick deployment in an emergency during rough weather conditions. There are three common

installations for the Dacon Rescue Scoop and which installation to choose depends on the design of

the vessel. The attachment chains must be attached permanently and cut to a length that suspends

the inner aluminum tube ~100 mm below the railing in the rescue zone when deployed.

Common storage solutions: 1. Stored in a simple crib inside the railing/bulwark. It needs to be stored 250 mm + above the

deck with one support in the middle and the outer supports 500-1000 mm from each end.

Internal measurements in the supports need to be 350 mm in width and 600 mm in height.

Permanent chains attach to the hull/railing ensuring its ready to deploy.

2. Stored in a crib on top of or integrated with the cargo rail supports. The crib needs to have at

least the same internal volume to accommodate the Scoop but can be built wider and lower

to reduce the risk of damage from cargo handling. For example 600 mm wide and 400 mm

high. Permanent chains attach to the crib or the supports ensuring its ready to deploy.

3. Stored on A deck / boat deck above the rescue zone. Stored in the same type of crib as

alternative 1 inside the bulwark/railing on A deck. A crib similar to alternative 2 can be used

if lifting height is an issue. In that case a railing needs to be fitted inboard of the crib to

protect the crew. Permanent chains attach to the deck or bulwark ensuring its ready to

deploy.

Lashings For options 2 and 3 the Dacon Scoop needs to be lashed in to the railing to hold it in position. 3

lashing lines are supplied together with the Dacon Scoop and lashing points need to be provided

inside the railing by yard.

Crane Requirements

Lifting Speed at the hook to be at least 50-60 m / min. This

is from experience in heavy weather operation to be able

to lift a person clear of the seas before he is washed

through the net by the next big wave.

Outreach over the side to be + 7 m in the area from center

of Rescue Scoop to 50% of the Scoop length forward of

the Rescue Scoop. More outreach may be required if the

crane is at a high elevation from the water.

The crane controls should allow for simultaneous operation

of at least two functions (eg winch/slue, jib/slue, jib/winch).

The crane operator must have a good view of the Scoop

recovery zone and the area forward of the Scoop.

The crane must have sufficient lifting height to allow the

Dacon Rescue Scoop to be deployed and stowed in the

stowage cradle. The lifting height is measured from the

highest outboard obstacle to the crane hook and depends

on the Vertical Depth of the particular model that is being

installed. Please see explanatory drawing below.

Additional for Norwegian flagged vessels

Slewing ring shall be dimensioned for being used at 20 heel.

The runner (mantel) shall be as light weighted as possible. However, a plummet / ball etc. to pull the wire is not accepted.

Requirements given in REG 19897-01-17 No. 4 shall be met.
