XSee the no.of strands & wire in each strand..for ex : 6x24,6x37,also measure dia of wire rope and from dia & construction you can find the SWL
Q. 2015) What is mediterranean moor & baltic moor ?
X
The MEDITERRANEAN MOOR consists of making a ship fast stem-on to a berth with the bows held in position by the anchors
The Baltic Moor This method of mooring a ship is employed when a vessel is to lie alongside a quay, the construction of which is not sufficiently robust to permit ranging of the ship during bad weather.
Q. 2016) You are on a chemical tanker & received order to load a cargo (say xyz) , how you will go about loading this cargo ?
XAns: first check type of cargo & whether mentioned in cert of fitness or not,if not check with class or flagstate administration whether vessel can load this particular cargo or not,if so get the new cargo endorsed in cert of fitness by flag state administration & then normal loading procedure
Q. 2017) What is CAS (condition assessement scheme) ?
X
CONDITON ASSESMENT SCHEME
ƒÞ Operation of oil tankers of certain specified categories beyond the specified date is permitted, subject to compliance with the CAS.
ƒÞ Procedure for preparation, conduct of survey, reporting and certification are given in the amendment 2001 to MARPOL 73/78.
ƒÞ CAS involves enhanced surveys along with thickness measurement of various hull members.
ƒÞ CAS surveys shall be carried out concurrently with intermediate or renewal surveys when the enhanced survey programme is applicable as per SOLAS chapter XI.
ƒÞ The surveys have to be carried out by a recognised organisation (RO), which is authorized by the administration.
ƒÞ Thickness measurement (TM) firm is a qualified company certified by the RO.
ƒÞ Not less than two qualified exclusive surveyors of the RO shall carry out the survey.
ƒÞ The surveyor must have experience of conducting renewal surveys and must undergo appropriate training and familiarization programme.
ƒÞ Thickness measurement shall be carried out by the certified TM firm in the presence of the surveyor of the RO.
ƒÞ CAS applies to surveys of hull structure in way of cargo tanks, pump room, cofferdams, pipe tunnels, void spaces within the cargo area and all ballast tanks including the fore peak and aft peak tanks.
ƒÞ In addition to overall surveys of the above spaces, it also includes close up surveys of structural member such as bulkheads, web frames, deck transverses, bottom transverses and all connected structural members.
ƒÞ Proper access must be provided for the close-up survey.
ƒÞ Tank coatings and corrosion protection system shall be inspected. Good coating need not be removed.
ƒÞ Thickness measurement shall be carried out on all deck plates, bottom plates, three transverse sections including at least one in way of a ballast tank, structural subject to close-up surveys, suspect areas, wind and water strakes, internals of fore peak and aft peak tanks and exposed superstructure decks
Q. 2018) Ror cards- aground v / l
XQ. 2019) What is type 1 , type2 , type 3 chemical tankers ? which one is having stringent criteria ?
X
IMO Ship Type 1
is a chemical tanker intended for the transportation of products considered to present the greatest overall hazard. The quantity of cargo required to be carried in a Type 1 ship should not exceed 1,250 m3 in any one tank
IMO Ship Type 2
is intended to transport products with appreciably severe environmental and safety hazards which require significant preventive measures to preclude escape of such cargo. The quantity of cargo required to be carried in a Type 2 ship should not exceed 3000 m3 in any one tank
IMO Ship Type 3
is a chemical tanker intended to transport products with sufficiently severe environmental and safety hazards. These products require a moderate degree of containment to increase survival capability in a damaged condition. There is no filling restriction for chemicals assigned to Ship Type 3
Cargo Tank Location
2.6.1 Cargo tanks shall be located at the following distances inboard:
Type 1 ships: from the side shell plating, not less than the transverse extent of damage specified in 2.5.1.1.2, (B/5 or 11.5m whichever is less), and from the moulded line of the bottom shell plating at centerline, not less than the vertical extent of damage specified in 2.5.1.2.3, (B/15 or 6 m whichever is less), and nowhere less than 760 mm from the shell plating. This requirement does not apply to the tanks for diluted slops arising from tank washing.
.2 Type 2 ships: from the moulded line of the bottom shell plating at centerline, not less than the vertical extent of damage specified in 2.5.1.2.3, (B/15 or 6 m whichever is less), and nowhere less than 760 mm from the shell plating. This requirement does not apply to the tanks for diluted slops arising from tank washing.
.3 Type 3 ships: no requirement"
