Welcome to the website where you can find answers for the Computer Based Test (CBT) also known as Crew Evaluation System (CES) on the subject «Separators, ALCAP Lube Oil System». This site will help you as a marine specialist improve your knowledge with the help of open information, where you can find questions as well as answers for them. CES/CBT based on practical information and marine specialists experience.
CES & CBT tests developed for evaluating seaman basic knowledge by Seagull Company (rebranded as «OTG»), is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW.
CES tests have proven themselves as good tools for the selection and recruitment process, as well as advancing the level of knowledge of the current officers and crew. Ocean Technologies Group use various subjects for question creation, which includes:
Crowd and Crisis Management;
Integrated Navigation System (INS);
Ballast water management;
Handling and Stowage;
Vessel operation management and safety;
Marine engineering;
Maintenance and repair, etc.
Current test contains Seagull CES questions on the subject «Separators, ALCAP Lube Oil System». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Separators, ALCAP Lube Oil System» subject includes theoretical and practical information about lube oil system of an ALCAP separators. Knowledge of this information directly shows employee’s competence who holds a relevant post on a vessel, provides to understand operational rules and specifics of an ALCAP separators on a vessels, control liquid separation process, detect any malfunctions, be able to perform an emergency stop so that prevent system clogging or separator failure.
This page contains answers to Seagull CES CBT (Crew Evaluation System/Computer Based Test) test about Separators, ALCAP Lube Oil System, and serve as a database of questions and answers, using which seafarer can prepare to exams for getting certificate of competence, or just to challenge yourself with knowledge in this theme.

More detergent and dispersant additives are used in Lube Oils today:
To keep the engine clean and prevent accumulation of sludge particles.
To change the specific gravity of the Lube Oil to acceptable limits.
To increase the anti-friction property of Lube Oil.
The ALCAP Lube Oil system contains which components?
Separator (LOPX), Transducer, Recirculation Valve, EPC 400 and Water Valve Block.
Transducer, Drain Valve, Water Valve Block, EPC 400 and FOPX Separator.
Water Valve Block, LOPX Separator, Separator Sam’s adjustment tool and EPC 400.
Recirculation Valve, Transducer, Drain Valve, EPC 400 and LOPX Separator.
The ALCAP purifier for LO is:
Is basically a clarifier but uses water for oil displacement and sludge conditioning.
Is a clarifier with a gravity disc.
Is exactly like a conventional Clarifier.
The conditioning water is added through the pipe which is in the middle of the feed tube:
To prevent the turbulent contact between the conditioning water and Oil.
To give the flow of water the least resistance.
This is the most suitable design for the bowl.
The function of the back pressure valve is:
To set the pressure between the Minimum positive pressure and the Maximum pressure at which oil overflows.
To set the pressure at which the Purifier operates.
To set the pressure of the water block.
Which of the following statements is correct?
The dispersant additives in lube oil break up the contaminants into small particles and keep them in suspension.
From Stokes Law particle size does not affect separation.
Lube oil additives assist the separator to remove water from the oil.
A smaller volume means more dirt will be going into the lube oil.
Which of the following statements is correct?
The LOPX removes water by discharging with sludge and draining from the water outlet.
There are two paring discs in the outlet of the LOPX separator.
Water is added to the middle of the FOPX bowl.
The inlet for displacement and conditioning water for LOPX is different than that for FOPX 605-613.
Which of the following statements is correct?
The dispersant additives in lube oil break up the contaminants into small particles and keep them in suspension.
From Stokes Law particle size does not affect separation.
Lube oil additives assist the separator to remove water from the oil.
A smaller volume means more dirt will be going into the lube oil.
Which of the following statements is true?
In case of ALCAP FO Purifier, Displacement is added until “trigger point” is reached. In LO purifier ALCAP design this is not the case.
In both FO and LO ALCAP design, displacement water is added in the same way.
The addition of displacement water in ALCAP design is optional.
Why is a predetermined amount of conditioning water added to the bowl?
To ensure the sludge removed from the lube oil does not get hard, and an excessive amount of separated sludge will cause water to be detected by the transducer.
In case there is no water in the oil the transducer will need it to take a reference.
To displace the oil inwards to economise on oil losses.
The ALCAP lube oil separator is a clarifier and does not need water in the bow.
