UMAS MARITIME

Marmara · Turkish Straits · Türkiye

Nothing happens, because the tug is already there.

Escort on strait transits, towage at sea, bollard pull and vessel trials, crew supply and 24/7 emergency response — all run from a single operations desk.

02What we do

Five service lines, one operating discipline

Each line has its own technical requirements, yet all are run to the same standard of preparation, follow-up and reporting.

01

Escort Towage

A tug running ready to connect throughout the transit, against loss of steering or propulsion.

We provide escort tugs for strait and canal transits, sensitive cargoes and large-dimension vessels. Position, connection method and the communication plan are agreed before the transit.

02

Towage Services

Anything that cannot proceed under its own power, delivered safely to where it is going.

Inter-port tows of barges, pontoons, floating equipment and vessels with restricted manoeuvrability. Tow survey, towline arrangement, weather window and route plan are prepared before departure.

03

Trials & Testing

Unmeasured performance is performance on paper only.

Bollard pull tests for tugs and speed, manoeuvring and machinery trials for vessels. Test set-up, measurement and coordination of class and owner attendance are handled by us.

04

Crew Supply

Fully certificated personnel who know the job — on the day the need arises.

Masters, engineers, officers and ratings for tugs, workboats and shore operations. Certificate validity, STCW compliance and shift planning are tracked throughout.

05

Emergency Response

What is decided in the first hours determines the scale of the loss.

Response, tow to a place of safety and on-scene coordination in cases of machinery failure, loss of propulsion or loss of manoeuvrability. Requests are answered around the clock.

03Coverage

The waters we sit in, the currents we know

Regional knowledge is more than distance on a chart: current regime, transit rules, traffic density and weather windows. We know these in every area we work.

Marmara and the Turkish Straits

The Istanbul and Çanakkale straits and the Marmara ports are the centre of our escort and towage work. Traffic density, current regime and transit rules govern everything here.

  • İstanbul
  • İzmit
  • Gemlik
  • Bandırma
  • Tekirdağ
  • Çanakkale
  • Yalova

Turkish Coastline

We provide towage, trials and crew supply at ports and yards along the Aegean, Mediterranean and Black Sea coasts.

  • İzmir / Aliağa
  • Mersin
  • İskenderun
  • Samsun
  • Trabzon
  • Zonguldak
  • Antalya

Black Sea

For long-distance tows and escort work in the Black Sea basin, we plan around seasonal weather windows and ice restrictions.

  • Constanta
  • Varna
  • Burgas
  • Novorossiysk
  • Poti
  • Batumi

Mediterranean

On Eastern Mediterranean routes we run project-based tow operations and yard delivery voyages.

  • Pire
  • Beyrut
  • İskenderiye
  • Limasol
  • Trieste

04Operation types

Escort, towage, testing — each planned separately

An escort through a strait and a barge tow offshore do not belong under one heading. We treat each operation type separately.

Marine services
ESC

Escort

A tug held in readiness alongside vessels in restricted waterways or carrying sensitive cargo, against loss of steering or propulsion.

SEA

Sea Towage

Inter-port tows of barges, pontoons, floating equipment and vessels unable to proceed under their own power.

BPT

Bollard Pull Test

Measurement of a tug’s static pulling power; set-up, measurement and surveyor attendance organised for certification.

TRL

Sea Trials

Planning and running speed, turning circle, crash-stop and machinery trials after newbuilding or major repair.

STB

Standby & Readiness

Keeping a tug on station during high-risk loading, yard work, maintenance windows or expected heavy weather.

CRW

Crew Supply

Certificated masters, engineers and ratings supplied to tugs and workboats, with shift and certificate tracking.

05How we plan

From enquiry to casting off, every step has an owner

In tug work the outcome is decided at the planning desk, not on the water.

  1. 01

    Enquiry and scope analysis

    Operation type, vessel or unit dimensions, area, dates and duration are recorded. A question not asked here comes back as delay on site.

  2. 02

    Power and equipment calculation

    Required bollard pull, towline arrangement and spare gear are specified, allowing for wind and current.

  3. 03

    Clearances and coordination

    Port authority notification, transit permissions, pilot and agency coordination are completed.

  4. 04

    Operation and reporting

    Position and weather are monitored throughout, and the timeline and records are handed over at completion.

06Why us

The difference shows in how we behave when the job tightens

Uninterrupted access

Our operations line is open around the clock. A transit change at midnight is handled as quickly as a request in office hours.

Knowledge of the straits

Current regime, transit rules and traffic patterns are followed daily. We build the plan around them and cut down the surprises.

Certificated crew

Every person we put on site has documentation verified beforehand. An operation stopped by missing paperwork is not our way of working.

One point of contact

You do not chase separate people for planning, field work and documentation. Each file has a named owner.

Measurable output

Test and operation results are reported together with their conditions. The circumstances behind a figure are on record too.

Realistic commitment

We do not promise an hour or a pull we cannot deliver. An optimistic commitment made to win the job costs both sides on the water.

07From the field

The work we describe has photographs behind it

This section is not for stock imagery; it is our own operational record. Every entry belongs to a real escort transit, tow voyage or trial.
