ON-SITE ASSESSMENT
Tell us the symptom, the yacht name / length and the marina; if needed, we will pin down the problem together with an on-site assessment. A photo or a short video is enough.
02Support capabilities
Alongside the core services, our fabrication, on-site assessment, testing, maintenance and system electrical capabilities let one team run the job from start to finish.
All servicesREFIT & FABRICATION
TIG welding, stainless fabrication, pipe fabrication, brackets and bases, equipment removal and refitting, and dry-dock technical work.
ON-SITE ASSESSMENT & TECHNICAL REPORTING
System inspection where the boat is, fault diagnosis, pre-refit technical assessment and reporting for owners / captains.
TESTING & COMMISSIONING
Commissioning new installations, revisions and post-refit systems with function, pressure, leak and performance tests.
PREVENTIVE MAINTENANCE & TROUBLESHOOTING
Start- and end-of-season checks, scheduled maintenance plans and systematic fault finding.
SYSTEM ELECTRICAL & CONTROL INFRASTRUCTURE
The electrical and control connections that mechanical systems need to run.
03Our approach
We assess a fault not through a single component, but within the integrity of the whole system.
Field experience that began in the Tuzla shipyards and grew on mega yacht, new-build and refit projects.
Pumps, lines, valves, controls and electrical infrastructure are assessed together with how they connect.
Cross-discipline coordination with mechanical engineering support and our partner Nice Marin Elektrik.
The right material, the right workmanship, a serviceable installation, a reliable system and a controlled handover.
Every job ends with function tests; the system is handed over running and checked.
Written reporting with findings, work done, materials used and before / after photos.

04Refit & New Build
Mechanical Systems · Piping · Hydraulics
Mechanical system refit, piping replacement, hydraulic renovation, tank, pump and sea water systems; testing, commissioning and technical coordination.
05How we work
Our goal is not just to get a system running again, but to hand it over correct and serviceable.
The system is inspected where the boat is, under real operating conditions.
Symptoms, faults and the condition of the existing installation are recorded.
The problem is assessed together with the system it belongs to; the root cause is identified.
Scope, materials, time and cost are defined and shared.
The approved scope is carried out with the right materials and a serviceable installation.
The system is run; function, leak and performance checks are made.
Findings, work done, materials used and before / after photos are reported.
Share the system, the marina and what you need; we will plan the first step together.
SERVICE REPORT
Before / after photo reporting. Test values are added to the report depending on the scope of work.
06Projects
Boat names are not shared without the client’s consent. Case details are being updated with photos as clients approve.

08Service area
Same-day technical service available from our Antalya base. 24/7 contact support for genuine emergencies.
Availability is confirmed by phone depending on workload.
09Technical notes
The right questions, a sound technical approach. Short, clear notes on yacht systems.
All notesWatermaker
In a watermaker that will stand idle for a long time, sea water left in the membranes can cause biological growth and fouling. The manufacturer’s preservation / pickling procedure protects the membrane; chemical, mix and contact time vary by model.
Read noteBilge
Pump selection weighs compartment volume, mounting position, hose size, discharge head and the electrical system together. The rated flow on the label is not enough on its own; real-world capacity is lower.
Read notePumps
Frequent cycling usually comes from low pre-charge in the expansion tank, a small leak in the plumbing, a faulty check valve or a wrongly set pressure switch — and it wears the pump out early.
Read noteHydraulics
Overheating can come from low oil level, dirty or wrong-viscosity oil, a clogged filter, a relief valve constantly bypassing, internal leaks or insufficient cooling. Heat shortens the life of both oil and seals.

Can’t find your answer? Just tell us the system and the marina.
Ask a questionWe are based in Antalya. We provide regular service in Antalya, Kemer, Kumluca, Finike, Demre, Kaş, Manavgat and Alanya (approx. 250 km), project-based work in Fethiye, Göcek, Marmaris, Bodrum and Muğla, and large refit and new-build projects across Türkiye.
Same-day technical service is available at Setur Antalya Marina, the fishing harbour, Kaleiçi / Old Harbour and Kemer, subject to workload. For genuine emergencies we provide 24/7 contact support.
The fastest way is WhatsApp: share the boat type and length, the marina, the system concerned and a short description; photos and videos speed things up. If needed we survey on site; scope, materials and timing are set out in the quotation.
The electrical infrastructure mechanical systems need — pump, motor and control connections (12/24 V DC, 230/400 V AC) — is within our scope. Full marine electrical, automation and navigation electronics work is coordinated with our partner Nice Marin Elektrik.
Warranty terms for workmanship and the equipment used are stated separately on the quotation, according to the scope of work and the manufacturer’s conditions.
The system is tested and commissioned before handover, with a service report covering findings, work done, materials used, before / after photos and recommendations.
Each service page lists the systems we have service experience with and those common in the industry, separately. Brand names do not imply authorized service status; manufacturer documentation applies to all work.
Next step
Share the system, your marina and what you need; if necessary we start with an on-site survey.
